You'll need "spatch", from coccinelle.

You can install this on Fedora using:
   yum install coccinelle

To run, invoke this:
   spatch -sp_file pyarg-parsetuple.cocci buggy.c 

This gives this output:

[david@brick static-analysis]$ spatch -sp_file pyarg-parsetuple.cocci buggy.c
init_defs_builtins: /usr/share/coccinelle/standard.h
HANDLING: buggy.c
buggy.c:13: Mismatching type of argument 1: expected "int *" but got "unsigned long *"

which correctly detects an issue seen in socket.htons() on 64bit big endian machines
